In 104 cases of control group STI was 0.3188±0.046, whereas in 99 cases of patient group STI was 0.3124±0.0585. In the 50 cases in which impedence cardiogram, carotid artery pulse wave and ultrasonic Doppler method were done simultaneously, the STI was 0.362±0.0414, 0.384±0.0621 and 0.3156±0.056 respectively.
Results of ultrasonic Doppler on lumbar muscle showed maximal blood flow and mean blood flow velocity increased (0.17±0.02) kHz and (0.09±0.01) kHz respectively than that before operation(P< 0.05).
The results of lung function(FEV 1, RV, TLC), arterial blood gas analysis (PAO 2, PACO 2) and color Doppler echocardiography (CO, CI, FS, EF, PAP) were analyzed before and 3 month after LVRS in 26 cases.
Methods We measured and analyzed lung function(FEV1?RV?TLC),arterial blood gas analysis (PO 2?PCO 2),and color Doppler echocardiography (CO?CI?FS?EF?PAP) in 20 COPD patients before and 3 months after LVRS.
Left ventricular diastolic function and left ventricular end-diastolic pressure(E/Em) were studied using Doppler echocardiography and tissue Doppler imaging(TDI).
Each subject was examined using Doppler ultrasound assessment of blood flow in the middle cerebral artery (MCA), Doppler echocardiography, and spiroergometry.
When stroke MRI is available, other imaging procedures such as CT and Doppler ultrasound may be unnecessary in hyperacute stroke patients as vessel occlusions in the circle of Willis as well as ICH are readily demonstrated or excluded.
Continuous and simultaneous measurement of cerebral vessels by ultrasonic Doppler is thought to be the only way to establish the detailed blood flow changes during smoking.
An ultrasonic Doppler method was used to monitor flow velocities in basal cerebral arteries in 21 patients with spontaneous subarachnoid hemorhage (SAH).
Ultrasound Doppler echography (USDE) of large peripheral blood vessels was performed in 110 patients with fractures in diaphyses of long tubular bones of the lower extremities.
Before and after the PTCA the changing of velocity flow patterns under rest and stress conditions with a handgrip-maneuver were measured with a noninvasive transthoracic ultrasound Doppler system.
While at the moment there is no atraumatic method for measuring cerebral blood flow in man, it is recommended to measure blood flow velocity with the ultrasound Doppler technic in the common carotid artery.
Each subject was examined using Doppler ultrasound assessment of blood flow in the middle cerebral artery (MCA), Doppler echocardiography, and spiroergometry.
Echo enhancing agents are suited to lessen the restrictions of tm, Doppler, and color Doppler echocardiography by physics and to better visualize the problems resolving.
The number of diagnostically utilizable Doppler signals can be significantly increased by using left ventricular contrast medium in diagnosis of aortic valve stenosis by means of Doppler echocardiography.
